Not only dirt particles but also water droplets have a direct effect on components of the injection system. This is particularly important for modern common rail systems, which place high demands on fuel quality. Fuel pre-filters from MANN+HUMMEL reduce the level of contamination of the fuel with water even before the feed pump in the low-pressure circuit, thus reliably protecting the injection system. MANN+HUMMEL offers also economical, pressure-loss optimized and high-flow inline filters.
